Professional Applications & Engineering Value
These 2-56 UNC rounded head Phillips screws deliver critical engineering solutions where precision and durability are paramount. Manufactured from 18-8 Stainless Steel with a passivated finish, they effectively combat corrosion in moisture-rich or chemical-exposed settings, reducing maintenance frequency and lifecycle costs. The coarse UNC threading and Class 2A fit enable rapid assembly with minimized cross-threading risks, while the fully threaded design ensures consistent clamping force across the entire 3/4" length. Ideal for electronics enclosures, machinery panels, and instrumentation, these screws provide reliable fastening under dynamic loads, backed by 100,000 psi tensile strength to prevent mechanical failure in demanding industrial applications.
Specification Summary & Compliance
This fastener maintains Class 2A thread fit per UNC standards with precise dimensional control as specified in ASME B18.6.3. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety requirements for industrial components.
